Use the gcf and the distributive property to express the sum as a product 18+27
Answer:
45
Step-by-step explanation:
18+27=9(2+3)=9(5)=45
The sum of the numbers 18 and 27 will be 45.
What is the greatest common factor?The largest factor of the two numbers which divides both the numbers is called as greatest common factor or GCF. The greatest common multiple is the common number multiplied by both numbers.
The distributive property of binary operations in mathematics generalizes the distributive law, which states that in elementary algebra, equality is always true.
Given sum is 18 + 27. The greatest common multiple between the two numbers is 9 take it common and then solve.
E = 18+27
E =9(2+3)
E =9(5)=45
Therefore, the sum of the numbers 18 and 27 will be 45.

Answer:
Step-by-step explanation:
These triangles are similar triangles, so there is a number that you can multiply the sides of TUV to find the side lengths of QRS. looking at the triangle, the similar sides are RS being similar to UV and RQ being similar to UT.
If RS~UV, then there is a ratio between them. 54/36=1.5. The ratio is 1.5.
RQ~UT, and by a factor of 1.5, so divide RQ by the scale factor. 24/1.5=16. UT=16=x+5.
x+5=16, subtract 5 from both sides.
x=11

The Sognefjord is the deepest fjord in Norway at 1,308 metres (4,291 ft) If a submersible floating on the surface was to dive vertically at a rate of 35 meters a minute, how many minutes would it have been diving when it reached a point 48 meters from the bottom of the fjord?
Answer:
36 minutes
Step-by-step explanation:
Depth of the fjord = 1308 m
Rate at which the submersible dives = 35 meters/minute
Distance to the bottom of the fjord should be 48 m
Distance the submersible has to go underwater is [tex]1308-48=1260\ \text{m}[/tex]
Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives
[tex]\dfrac{1263}{35}=36\ \text{minutes}[/tex]
The time taken by the submersible to dive the required distance is 36 minutes.

Shelter A has 500 beds and is 90% occupied. Shelter B is 60% occupied, the ratio of beds in Shelter A to Shelter B is 15:16
Answer:
800 bedsStep-by-step explanation:
Shelter A has 500 beds and is 90% occupied.
Number of occupied beds:
500*0.9 = 450The ratio of beds occupied in Shelter A to Shelter B is 15:16
450/x = 15/16x = 450*16/15x = 480Number of occupied beds in Shelter B is 480 which is 60% of total. Total number of beds is:
480/0.6 = 800Answer:
Answer:there are 900 beds in shelter B
Step-by-step explanation:
Shelter A has a capacity of 300 beds and is 80% occupied. This means that the number of beds in Shelter A that would be
80/100 × 300 = 0.8 × 300 = 240 beds.
Let x represent the capacity of Shelter B. Shelter B is 45% occupied. It means that number of beds in Shelter B that would be occupied is
45/100 × x = 0.45 × x = 0.45x beds.
Total occupancy of shelter A and shelter B would be
240 + 0.45x
The ratio of the occupancy of shelter A to shelter B is 16:27
Total ratio of occupancy = 16 + 27 = 43
Therefore
27/43 × (240 + 0.45x) = 0.45x
27(240 + 0.45x) = 0.45x × 43 = 19.35x
6480 + 12.15x = 19.35x
6480 = 19.35x - 12.15x = 7.2x
x = 6480/7.2 = 900

You have $20 to spend on taxi fare. The ride costs $5 plus $2.50 per mile. Write an inequality to determine how many miles you can ride for $20.
Answer: Maximum 6 miles
Step-by-step explanation: In total you have $20.
Base fare of taxi is $5.
Per mile cost is $2.50.
Your total cost is where x is the number of miles. Since you're on a budget of maximum $20, the cost should be less than or equal to $20. We can write:
To find how many miles we can write, let's solve the inequality:
.
This means 6 is the maximum number of miles you can ride with $20.

Pleaseeee helpp answer correctly !!!!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!!!
Answer:
x = 7; y = 11
Step-by-step explanation:
AB = x
AB = CD
CD = 7 so....
x = 7
AD = y + x
AD = BC
BC = 18 so...
y + x = 18
y + 7 = 18 subtract 7 from 18
y = 11
Answer:
x = 7
y = 11
Step-by-step explanation:
Do you see those little arrow marks? Those indicate that if a side has those marks, they have the same length. If a side with one arrow is 7 units long, then it means that x = 7, because the side with x also has one arrow. Then, just plug in 7 into the y+x equation, and set it equal to the other side. (18).
y + 7 = 18; subtract 7 from both sides, to get x = 7; y = 11.
Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day, and good luck on your assignment. :)

In a recent year, 23.7% of all registered doctors were female. If there were 54,400 female registered doctors that year, what was the total number of registered doctors? Round your answer to the nearest whole number.
Answer:Total number of registered doctors=229, 536
Step-by-step explanation:
Let the total number of registered doctors be represented as x
Such that 23.7 % of female registered doctors is totals 54,400
To find the total number of registered doctors, we use the equation
23.7% x -= 54,400
Solving the equation we have
0.237 x x= 54,400
x= 54,400/0.237
x= 229, 535.86 rounded to 229, 536
x=Total number of registered doctors=229, 536

Prove that each of the expressions below are equivalent by evaluating the expressions given. Given g = 3.
15g-2(2g+6) and 11g-12
Answer with Step-by-step explanation:
We are given that
g=3
[tex]15g-2(2g+6)[/tex] and [tex]11g-12[/tex]
We have to prove that two expressions are equivalent by evaluating the expressions given
[tex]15g-2(2g+6)[/tex]
Substitute the value of g in the given expression
[tex]=15(3)-2(2(3)+6)[/tex]
[tex]=45-2(6+6)[/tex]
[tex]=45-2(12)[/tex]
[tex]=45-24[/tex]
[tex]=21[/tex]
[tex]11g-12[/tex]
Substitute the value of g in the given expression
[tex]=11(3)-12[/tex]
[tex]=33-12[/tex]
[tex]=21[/tex]
Hence,
15g-2(2g+6) = 11g-12 when g=3
